[Buildroot] [PATCH v4 01/12] toolchain/gcc: Add host-{flex, bison} dependencies for GCC 4.2, 4.3, 4.4

[Mischa Jonker <Mischa.Jonker@synopsys.com>]

Note that gcc doesn't use the package infrastructure, and needs proper
$(HOST_MAKE_ENV) and $(TARGET_MAKE_ENV) to be able to find host-flex/
host-bison.

Original patch by Thomas Petazzoni.
